Any path which guides people to understand themselves requires discipline and sincerity in daily life, and this is true for yoga. I don't know much about it, but to the best of my knowledge yoga can be adopted by anyone regardless of colour, religion or social background. Yoga helps everyone become truly human and realise his spiritual potential. As a nun I find yoga helps me to put into practice the teachings of the holy Bible:
Neither shall they say, lo here or there, for behold, the kingdom of God is within you.
Inside us there is a rich life which is still unknown because of the superficial life we are used to, and because we lack a personal relationship with God. This inner life is exactly what the yogic practices help us find and because of this I can say that yoga is a way of liberation.
The process of awareness, concentration and meditation allows us to reach that point which saints reach, and yoga shows us the way to progress along that path. Swami Amritananda is a shining example of godliness, union through ashram life. In the ashram everyone who comes to listen and learn is welcome, and they realise many things simply by being there. I tell every one I meet that human beings can transcend their limitations through yoga. I feel it is necessary for all people who understand the discipline of yoga to work actively in spreading this message.
